用途: Biotin-PEG2-Mal is a PEG derivative containing a biotin group and a maleimide group for labeling and crosslinking cysteines and other sulfhydryls. The maleimide group reacts specifically with sulfhydryl groups (at pH 6.5-7.5) to form a stable, irreversible thioether linkage. The hydrophilic PEG spacer increases solubility in aqueous media and increases membrane impermeability of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules. 物理化学性质: CAS号:305372-39-8 常用中文名:N-生物素基-N'-(3-马来酰亚胺基丙酰基)-3,6-二氧杂辛烷-1,8-二胺 常用英文名:Biotin-PEG2-Mal 分子式:C23H35N5O7S 分子量:525.618 密度:1.3±0.1 g/cm3 沸点:897.0±65.0 °C at 760 mmHg 熔点:N/A 闪点:496.3±34.3 °C 储存条件:-20 ℃ |
